The measured building.

Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.

Source photographs: 464
Identified objects: 4872
Verified printed values: 12046
Disputed values: 20

464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass review of public/archive/drawings/complete-upright/IMG_0977.webp. Actual orientation recorded; source regions refer to displayed access-image coordinates. No modeling or exact room geometry inference. Partial timed visual review: Additive selected remaining-region review; prior queue, OCR and packages consulted. Prior verified readings reused without duplication. Partial extraction only; no modeling. Partial timed visual review: Bounded additive remaining-region review; prior queue, OCR and reports consulted. No full coverage or modeling. Partial timed visual review: Source-local view inventory and selective notes/individual properties; repeated-photo correspondence does not establish revision equivalence, installed quantity or exact geometry.

Highlighted reading: ⅝" BOLT. Selected printed source evidence; partial review.

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
